To all whom it may concern:

Be it known that I, HENRI OHRETIEN HOCKENJOS, residing at 3 Boulevard de Belleville, Paris, in the Republic of France, engineer, do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement.

The present invention relates to continuous spinning frames of the floating traveler ring type, and has for its object the improvement of the movable rings of these machines.

It consists in resting the ring in a special manner on its support, in order to specially lighten its rotary and floating motion and thereby make it extremely easy to drive.

Like those already known, the device according to this invention comprises the traveler ring, its retaining collar, the ring plate and a washer of paper or thin card interposed between the ring plate and the floating ring; and it is characterized by a special means for supporting this washer on the ring plate, and the ring on the washer.

In the accompanying drawing, Figures 1 to 8 show various constructions of the device to this invention.

Like letters indicate like parts throughout the drawings.

In the existing systems the traveler ring in many cases is supported on the ring plate by means of a paper washer, which separates these two parts and is arranged freely between their adjacent faces, for the purpose of preventing them from engaging together and for lessening the friction between them. Experience has shown that,v unless this washer (Z is carried around by the rotary motion of the traveler ring, the latter gradually slows down and finally stops; but this carrying around of the washer proceeds very imperfectly, I or even ceases altogether, when the washer is pressed, by the weight of the ring, between the upper face of the ring plate and the lower face of the traveler ring. The present invention overcomes this defect by means of novel arrangements of the con tact surfaces 6 and f of the ring and ring plate, on the washer (Z. This result is obtained in a very simple manner by arranging the contact surfaces of each piece on the washer in such a way that instead of being directly opposite each other, they are in different vertical planes at their point of contact with the washer. The several figures of the drawings illustrate this characteristic under different forms. They all represent radial sections or partial sections of rings and ring plates. It will however, be understood that the invention is equally applicable to any other type of ring that rests directly on the ring plate or is separated therefrom by a washer of paper.

In Fig. 1, which representspartly in section and partly in elevationa ring mounted on the plate of the frame, the washer {Z rests on the ring plate Z) by merely a fraction of its width Z, the annular contact crown f of these two-pieces being reducible, if necessary, to a circumferential line. The ring in turn rests on the washer (Z by means of an annular crown c, which may also be reduced to a circumferential line. The two concentric crowns c and f are notsuperimposed, and therefore the ring can never rest on the ring plate through the agency of the washer (Z, but rests only on a crown of the washer free from all contact with the ring plate. Thus, during the movement of the ring the Zone situated directly under 9 on the lower face of the washer cannot rest on the upper face of the ring plate, and, on the upper face of the washer the Zone situated in the same vertical plane as f cannot come in contact with the traveler ring, which is therefore mounted loose on the washer. Under these conditions of mounting, the ring has a particularly easy movement of rotation on the crown which serves it as a base, and it carries the same around without any retardation of its own motion, thus acting as a gyroscope and seeming to float above the washer (Z, with which it comes in contact in only an intermittent manner. This washer appears to be animated by special vibrations and forms a kind of supple and elastic sup port for the ring, thus facilitating the rotation of the latter in a remarkable degree. Without desiring to cnunciate the physical or kinematic theory of these phenomena, it may nevertheless be mentioned that, by liberating the zones of the washer that are opposite to the surfaces of contact with the ring and ring plate, the desired conditions of movement are modified in a favorable direction. Any other arrangement presenting the same characteristic will equally furnish the same result.

Figs. 2 to 8 relate to different modifications of Fig. 1, in all of them it will be seen that the washer cl supports the ring; consesurfaces (2 and f are reduced to circumferential lines, it is preferable not to make these contacts in the form of sharp edges which would quickly wear out the washer carrying the ring; and it is better to employ edges that are dulled by a slight flattening or by curving the surface. With this object the ring and ring plate in Fig. 1 are provided with flanges of semi-circular section. The constructions shown in the subsequent figures are designed upon the same principles.

Fig. 3 shows, on a larger scale, the device giving the best propulsive effect. The ring plate shown in this figure is characterized essentially by a very gentle slope g, the up per edge of which, j, forms the support of the washer (Z. This slope may be either toward the interior or exterior of the ring. Different applications of this arrangement are shown in Figs. 2, 4, 5 and 6.

Fig. 2 represents a ring plate characterized by a slope g inclined toward the interior of the ring plate. Fig. 4- shows this inclined surface provided with a groove h below the zone of contact between the ring and the washer. In Fig. 5 this zone is charged with a solid lubricant 71 In Fig. 6 the contact between the washer (Z and the ring plate I) is at the upper part of a slope g inclined in the opposite direction to the surface 9; and a groove It may also be provided under the surface (6), of contact between the ring and the washer.

Fig. 7 represents a ring plate the upper horizontal bearing surface of which has been grooved along the center of its width, thus forming two surfaces of contact, f and f between the washer and the ring plate, the surface 6 with which the traveler ring rests on the washer (Z being in the same vertical plane as the gap h separating f and f. The arrangement in Fig. 8 is the converse of that shown in Fig. 7. Numerous other profiles can also be imagined.

Apart from the case of movement furnished by the various arrangements described, the invention presents another advantage. The draft set up by the floating ring when driven at its normal speed causes a current of air from the lower part of the ring plate toward the upper part; and since the air can pass freely between the washer and ring plate, as well as between the washer and the ring, the accumulation of fibers and dust between the retaining collar 0 and the ring plate is prevented. Hence erases the movement of the retaining collar is never hampered, and consequently that of the ring maintains its original smoothness.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is:
